When I am hungry

Caiello solved #101 and showed many interesting lines about it.The author of this puzzle is I.Shiffmann . And after such a big horse-hunting , i think we need something more light - a puzzle again from A.Troizky :

white to play and win

                                             Black king can escape:

                                               Black has such a possibility:

You are absolutely right . But let's change position a bit and suppose black just checked from ' b4 ' - can white win ?

                                          2.Bc6 doesn't work :

                                        There is direct check  4...Qf5+:

That took me a while. I smacked my head when I saw the solution though. 

 to Elona and   to Caiello !

Does anybody else see the solution ?

Caiello worked hard on this puzzle and i think , he has the right to post full solution , when decides to.

OOoooh very nice, didnt recognise that pattern coming up. Whenever i try to create something like that, even if it "works", i cant get it to fully work as theres easily a better solution
